Abstract

A method for replacing a roll cage of an off-road vehicle is provided. The off-road vehicle has a frame and the roll cage affixed to the frame. The frame has a plurality of roll cage supports. The roll cage has a plurality of legs, and each of the legs is welded to a respective one of the roll cage supports of the frame. The method includes cutting off the roll cage from the frame, providing a replacement roll cage for removably affixing to the frame, positioning the replacement roll cage onto the frame such that legs of the replacement roll cage are supported on the roll cage supports, aligning an opening of a mounting flange of each leg of the replacement roll cage with a corresponding opening of each roll cage support, and fastening the legs of the replacement roll cage to the roll cage supports.

First claim

What is claimed is:

1. A method for replacing a roll cage of an off-road vehicle, the off-road vehicle comprising a frame and the roll cage affixed to the frame, the frame comprising a plurality of roll cage supports, the roll cage comprising a plurality of legs, each of the legs being welded to a respective one of the roll cage supports of the frame, the method comprising:
cutting off the roll cage from the frame;
providing a replacement roll cage for removably affixing to the frame, the replacement roll cage comprising a plurality of legs for removably affixing to the roll cage supports of the frame, each leg of the replacement roll cage comprising a mounting flange, the mounting flange comprising an opening for receiving a fastener;
positioning the replacement roll cage onto the frame such that the legs of the replacement roll cage are supported on the roll cage supports;
aligning the opening of the mounting flange of each leg of the replacement roll cage with a corresponding opening of each roll cage support;
fastening the legs of the replacement roll cage to the roll cage supports.

2. The method of claim 1 , wherein said cutting comprises cutting each leg of the roll cage at a point above a respective roll cage support.

3. The method of claim 2 , wherein the point above which each leg of the roll cage is cut is above a weld between the leg and the respective roll cage support.

4. The method of claim 2 , wherein the point above which each leg of the roll cage is cut is up to 10 mm from an upper surface of the respective roll cage support.

5. The method of claim 1 , further comprising removing residue material of the roll cage left on the roll cage supports after said cutting.

6. The method of claim 5 , wherein said removing comprises grinding the residue material of the roll cage.

7. The method of claim 5 , further comprising buffing the roll cage supports of the frame after said removing.

8. The method of claim 5 , further comprising applying a protective coating to the roll cage supports after said removing.

9. The method of claim 1 , wherein:
the mounting flanges of the legs of the replacement roll cage have lower surfaces that are parallel to one another; and
said positioning comprises placing the lower surfaces of the mounting flanges of the legs of the replacement roll cage in parallel with upper surfaces of the roll cage supports.

10. The method of claim 1 , wherein said fastening comprises:
inserting a fastener into the opening of the mounting flange of each leg of the replacement roll cage and into the corresponding opening of the roll cage support; and
securing the fastener with a fastener receiving member.
